Output Messages
The GNU variant of dd as supplied with Linux does not describe the format of the messages displayed on standard output on completion, however these are described by other implementations e.g. that with BSD.
Each of the "Records in" and "Records out" lines shows the number of complete blocks transferred + the number of partial blocks, e.g. because the physical medium ended before a complete block was read, or a physical error prevented reading the complete block.

Famous quotes containing the words output and/or messages:
“Lizzie Borden took an axe
And gave her mother forty whacks;
When she saw what she had done,
She gave her father forty-one.”
—Anonymous. Late 19th century ballad.
The quatrain refers to the famous case of Lizzie Borden, tried for the murder of her father and stepmother on Aug. 4, 1892, in Fall River, Massachusetts. Though she was found innocent, there were many who contested the verdict, occasioning a prodigious output of articles and books, including, most recently, Frank Spiering’s Lizzie (1985)
“The first of the undecoded messages read: “Popeye sits in thunder,
Unthought of. From that shoebox of an apartment,
From livid curtain’s hue, a tangram emerges: a country.””
—John Ashbery (b. 1927)
